SHEATHlNG-LATH.

SPECIFICATION forming part of Letters Patent No. 534,57' 1, datedFebruary 19, 1895. Application filed July 20, 1894:. Serial No. 518,122.(No model.)

To @ZZ whoml it may concern:

Be it known that I, MARSHALL C. NICHOLS, a citizen of the United States,residing at Viroqua, in the county of Vernon and State of Visconsin,have invented certain new and useful Improvements in Sheathing- Laths;and I do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in sheathing laths which arereversible, that is to say, having grooves to receive the mortar on bothsides, so that either side may be employed as the facing. y

Heretofore a reversible sheathing lath has been produced, h avinggrooves on each side, to receive the mortar, the grooves on one sidelying in the same plane or opposite to those on the other side. Thisconstruction, however, is objectionable, in that the grooves must be cutvery shallow, in order to have the necessary thickness of material toprovide the requisite strength, and even then, the lath is undulyweakened owing to the close proximity of the grooves on one side tothose on the other side.

My invention is designed to obviate the above and other objections andit consists in a sheathing lath having a number of inclined or beveledgrooves on both sides, arranged to break joints, and one side beingprovided with a less number of grooves than the other side, as will behereinafter fully described and claimed.

In the accompanying drawings, Figure 1, is a perspective view of asheathing lath constructed in accordance with my invention. Fig. 2, is asectional view of the same.

In the said drawings the reference numeral l designates a woodensheathing lath of suitable size, formed on both sides with grooves 2, toreceive the mortar, which grooves are.

a tapering groove 4, With beveled sides which' will engage,respectively, with corresponding grooves and tongues of adjoining laths,when secured to a building or other structure.

It will be noted that by thel above construc-Y tion and arrangement ofVthe grooves, they may be cut much deeper than when they lie opposite orin the same planes with each other, Without unduly weakening the laths.Again it sometimes happens, as in the case when a thin layer of mortaror plaster is to be used on the laths, that a less number of grooveswill be required to hold the same, than When a thicker layer isemployed. By making the laths With a less number of grooves on one sidethan the other, this contingency is provided for, thereby effecting asaving in the mortar or plaster.

Having thus fully described my invention, what I claim is As an improvedarticle a sheathing lath having a tapering tongue at one end and atapering groove at the other end with its outer sides beveled or flaringand a series of inclined grooves intermediate the said ends, differentin number, on both sides and located in dierent planes, so as to breakjoints, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
